Best practices for timing sequencer modules

Hi, I'm a new user to Reaktor seeking some insight on some timing issues I've come up against using the Multiplex 16 sequencer module. After trying a few different configurations, I've had the best results with the following chain of modules-

Sync Pls. (100% width) - Hold (minimum length)

Song Position (96 event output) - Modulo / 6 - this gives song position in 16th notes, wraps around to feed the position of 2 chained 16 Multiplex sequencers - outputs gate logic signals (0/1), these are multiplied by the output of the Hold module to convert gate-trigger

This makes for a pretty effective 32-step trigger sequencer, but I'm having trouble with the timing of about the first 4 steps - a sequence with all 4 consecutive 16th notes on or off triggers as expected, but anything other combination seems to cause unpredictable trigger behavior. Any ideas on what might be causing this, or suggestions for a cleaner solution? I've tried differently ordered variations of this to no avail…I guess I could just use an event table to do something similar, but I'd like to be able to send MIDI messages to toggle buttons on/off for x0x style sequencing.

I'm using Reaktor 5, if that matters..
